Constantinescu (2003:2) describes the object as "a patera with pagan (Germanic) gods representations". Remarking on the figures displayed on the patera, Todd (1992:130) writes: “In the centre sits a throned figurine of a female on a circular throne, holding a goblet in cupped hands. The encircling frieze represents a group of divinities, some in Classical guise, others with attributes more easily assignable to the Germanic pantheon. A powerful male god holding a club and cornucopia, and seated on a throne in the form of a horse’s head, is probably closer to Donar than to Hercules. A heroic warrior in full armour and wearing three hair-knots is plainly a barbarian kingly god, while a trio of goddesses presumably represents the German matres. The seated goddess who presides over the entire ensemble is also not easily placed in the Classical order. She is better viewed as a barbarian mother of the gods.” Photographs of the patera can be found here [1] and here [2]. See also Macleod (2006:174).
